N2PH-Does the job!  Time owned: 3 to 6 months
I had an LNR 40 through 10 meter end fed antenna and I liked it, but it was a bear to tune. After reading the reviews on the 4010 and talking to Dannie, I thought I would give it a try. No tuning was required!-the SWR’s for 40, 20, 15 and 10 were excellent. But, I am a CW operator and I love to tinker with antennas so I added about 4 inches of wire to the end and the SWR’s were even better.

But, who cares whether you have a SWR of 1.4 or 1.2 right? The key question is does the antenna work and it does. I run 40 watts or less and I have made numerous contacts all over the US and the world. I consistently get good reports. Is it a beam?-of course not, but this is a simple, very effective antenna which has worked great for me.

My set up-is the matchbox is at 30 feet and the antenna slopes down to 16 feet. I live in a very tough environment (the Jersey shore) where it is windy-average wind speed 15 MPH, and everything is affected by the salt air and this antenna seems well made to handle this tough environment.

I don't think you will be sorry if you buy one.

Impressed  Time owned: 0 to 3 months
I have only been using this antenna for about a week However, I have been using wire HF antennas since 1979 and have tried a lot of them. I came to the conclusion that there is no magic antenna: if you have wire antennas of approx. the same size, they are going to work about the same on the air. BUT, the difference with this antenna is that the end fed design makes installation much easier AND it does exhibit low SWR over the low end of various HF bands. I am making no claims of super performance on the air: it works about like any other wire antenna of similar length. But, my initial impressions are that this may be the best wire antenna I have ever used because it's easy to install and it loads without a tuner at certain spots.

Limited Power handling  Time owned: 0 to 3 months
I've had the antenna for about a week. It's mounted at 20 feet and fed thru about 100 feet of coax which serves as the counterpoise. I have a choke for common mode current in the shack. SWR, as measured at the transformer, on 40, 20 and 15 is fine and higher but still tolerable on 10 meters. On 40 meter CW the SWR starts to climb if I run more than about 300 watts while making long CW transmissions. I'm able to make similar transmissions while running 400 watts without noticing this problem on 20, 15 and 10 meters. It appears that the matching transformer may be heating up on 40 meters at the higher power levels. The antenna is rated at 1 KW ICAS but doesn't seem to live up to this rating on lengthy 40 meter CW transmissions which have a heavier duty cycle than SSB. I cannot comment on how the transformer behaves on SSB.

The literature that comes with the antenna notes: "Adjust your power to style of operation, make sure that transmit period is followed by same or longer period on receive in order to meet ICAS power rating."

Aside from the power issue, the antenna certainly works well enough. I've made numerous A/B comparisons on the Reverse Beacon Network with my ground mounted Hustler 6-BTV employing 50 20-foot radials. The end fed dipole results in stronger reports than the Hustler about half the time. The Hustler gets better reports about a quarter of the time - most often on distant DX - and both antennas produce similar reports about a quarter of the time.

I've often found it desirable to have more than one antenna along with the capability of rapidly switching back and forth between them to take advantage of whichever antenna seems to be performing better at the time. The addition of the EFHW-4010 4 band end fed dipole enables me to do just that.

Works as expected to replace individual dipoles for these bands  Time owned: 0 to 3 months
I needed a single, multi-band dipole, but didn't have a way of mounting a traditional dipole at this location. An End Fed dipole only requires two attachment points, and was the way to go for me. After install, I found the SWR to be commensurate with the values advertised by the manufacturer. The antenna exhibited low SWR on 40, 20, 15 & 10 Metres, and was easily tuned with the internal tuner in my Flex 6500.

INITIALLY, reception was TERRIBLE on all bands, with horrific noise. I sent e-mail to the manufacturer, including screenshots of the noise from my panadapter and waterfall. The manufacturer [correctly] diagnosed my problem as CMC [Common Mode Current] on the feed line, and suggested adding a Common Mode Choke. He recommended this choke: . I ordered it, and two days later it arrived. The choke COMPLETELY solved my noise problem, and this antenna now is a solid performer. Having a single 4-band antenna allows me to have four slices open on my Flex 6500 at one time. I couldn't be happier with the result!
